Interfering with the Earth’s climate system to counteract global warming is a controversial concept. However, relying solely on reductions in greenhouse gas emissions to bring climate risk to acceptable levels seems perhaps to be based on an overly optimistic view of the potential for human cooperation.

In his public lecture “Geoengineering Earth’s Climate: Crazy or Necessary,” Ken Caldeira, a Stanford University climate scientist, will discuss what is understood scientifically about geoengineering proposals to counteract some of the effects of high concentrations of greenhouse gases in the atmosphere, and places this scientific knowledge in a broader political and ethical context.

The Educating for Sustainability series, which brings environmental scholars and leaders to NYU for public lectures, is cosponsored by the Sustainability Task Force and the Environmental Studies program.
